Writeup from MB 104:

Northwest Africa 10443 (NWA 10443)

(Northwest Africa)

Purchased: 2015 Jul

Classification: Carbonaceous chondrite (CK3)

History: Purportedly found in Mauritania and purchased by Darryl Pitt in July 2015 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Separated, well-formed chondrules (apparent diameter 1.9±1.0 mm; one 10 mm × 7 mm) with grains of stained Cr-magnetite are set in an orange-brown matrix containing intermediate plagioclase, calcite and minor barite.

Geochemistry: Olivine (Fa7.7-41.6, FeO/MnO = 89-126, N = 3), orthopyroxene (Fs25.2-28.9Wo0.7-3.0, N = 3), augite (Fs12.3Wo45.7; Fs22.2Wo50.5, N = 2).

Classification: Carbonaceous chondrite (CK3). Possibly paired with NWA 10405 based on distinctive textures, similar silicate compositions and presence of secondary calcite.

Specimens: 22 g including one polished thin section at UWB; main mass with DPitt.
